Quote pyramids are for losers
Styling is subjective: For example, I find the mix of analogue, digital and textures in the 370 to be very jarring and awkward. I now prefer the exterior of the 370 to the 350, but I really didn't at first. In terms of the drive there's nowt much in it, but the 350 feels more raw and that appeals to me. I'd say the 370 is a fraction twitchier, but I preferred the steering and more planted feel of the longer wheelbase in the 350.
For looks, I'd have a 370 ragtop in Black Rose any day. For the drive, a solid HR 350 would be preferable, with a few £K in the pocket.
Meh, each to their own. Both good cars.
